viewtopic.php?f=420&t=6424Some stuff has changed since then (e.g. the IAP game had desperadoes, role investigators, and the silence mechanic), but a lot of stuff is the same. The IAP discussion talks more about role strategy, especially given that the spring game didn't have new players.
Main takeaway: Remember to use your powers!
In particular, remember to use pre-day powers on today, day 0, before midnight tonight. Otherwise they'll go to waste for the day!
